Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

with reference to the accompanying drawings: the novel telescopic baton comprises a front tube 11, a middle tube 12 and a grip 13 which are sequentially and telescopically nested, wherein positioning units are arranged between the front tube 11 and the middle tube 12 and between the middle tube 12 and the grip 13, and can be unfolded along with the middle tube 12 when extending out of the grip 13 and the front tube 11 when extending out of the middle tube 12 and positioned when the front tube 11 or the middle tube 12 extends out or retracts back to the limit position, so that the front tube 11 or the middle tube 12 is prevented from retracting/extending out in a use state/a non-use state.

To the positioning unit, through the positioning unit, not only can stretch out or can contract to the extreme position when the baton fixes a position, avoid the baton the condition that contracts back or stretch out to appear, but also can strengthen the use intensity between each tube coupling, make the baton still can keep complete state of stretching out under the state of knocking, the positioning unit has two and sets up relatively, it includes first linking arm 21, second linking arm 22, and be preceding, back dislocation set, the upper end of first linking arm 21 rotates with the upper end of second linking arm 22 to be connected, and by well pipe 12, the flexible drive of head tube rotates, the upper end of first linking arm 21 and the upper end of second linking arm 22 are coaxial setting, so both can all wind same axis rotation.

In order to avoid the phenomenon that the baton moves reversely when extending out or retracting to the limit position, the clamping piece 3 which is blocked when the front pipe 11 or the middle pipe 12 extends out or retracts to the limit position is arranged at the rotary connecting position of the first connecting arm 21 and the second connecting arm 22, after the baton extends out or retracts to the limit position, the first connecting arm 21 and the second connecting arm 22 do not rotate continuously, in order to avoid the phenomenon that the baton moves reversely under the influence of the first connecting arm 21 and the second connecting arm 22, the first connecting arm 21 and the second connecting arm 22 do not rotate continuously through the clamping piece 3, and therefore the state of the baton when extending out or retracting to the limit position is kept.

Further perfect, fastener 3 has card portion 31 and is blocked portion 32, and card portion 31 is located the preceding terminal surface of the upper end of first linking arm 21 or second linking arm 22, is located the rear end face of the upper end of second linking arm 22 or first linking arm 21 by card portion 32, realizes mutual joint through card portion 31 and blocked portion 32 to realize the card die, this kind of simple structure, convenient operation, excellent in use effect.

Further perfection, card portion 31 is the arc and extends along the axial direction of the upper end tip of first linking arm 21 or second linking arm 22 to be provided with two opposite archs 31-a at the left and right both ends of card portion 31, one of them arch 31-a is located the upper inner wall of card portion 31, another arch 31-a is located the lower inner wall of card portion 31, the card portion 31 of this kind of structure not only limits effectually, and simple structure can be restricted card portion 32 at the left end of card portion 31, right-hand member through two archs 31-a, thereby realize the joint to being blocked card portion 32.

Further perfection, the clamped part 32 is columnar and extends into the clamping part 31, and is positioned at the left end or the right end of the clamping part 31 through the two protrusions 31-a by extrusion, and is blocked by the two protrusions 31-a, the outer diameter of the clamped part 32 is consistent with the width of the clamping part 31, so that when the clamped part 32 moves in the clamping part 31, friction force can be kept between the clamped part 32 and the clamping part 31 all the time, the clamped part 32 has good stabilizing effect in the process of moving along the track of the clamping part 31, the distance between the two protrusions 31-a is smaller than the outer diameter of the clamped part 32, therefore, when the clamped part 32 passes between the two protrusions 31-a, the clamped part 32 needs to release certain external force to assist to pass through, after passing through, the clamped part 32 is clamped at the left end or the right end of the clamping part 31, under the effect of no external force, the clamped part 32 cannot pass through between the two protrusions 31-a, thereby realizing the locking.

Further perfection, the grip 13 and the first connecting arm 21, the middle pipe 12 and the second connecting arm 22, the middle pipe 12 and the first connecting arm 21, and the front pipe 11 and the second connecting arm 22 are rotatably connected and realized through the connecting piece 4; the connecting piece 4 comprises a fixed shaft 41 and a shaft sleeve 42, the shaft sleeve 42 is rotatably connected to the fixed shaft 41, the fixed shaft 41 is positioned at the head of the front pipe 11 or the middle pipe 12 or the handle 13, and the shaft sleeve 42 is positioned at the lower end of the first connecting arm 21 or the second connecting arm 22.

Further perfection, the shaft sleeve 42 is provided with a notch 42-a, the fixed shaft 41 enters the inner cavity of the shaft sleeve 42 through the notch 42-a to realize rotation of the shaft sleeve 42, the arrangement is convenient for installation of the shaft sleeve 42, the inner diameter of the inner cavity is consistent with the outer diameter of the fixed shaft 41, so that rotation of the shaft sleeve 42 can be realized, meanwhile, the caliber of the notch 42-a is smaller than the outer diameter of the fixed shaft 41, when the shaft sleeve 42 is installed, the notch 42-a needs to be expanded by means of certain thrust, and therefore, the shaft sleeve 42 cannot be separated from the fixed shaft 41 under the condition that no external force acts on the shaft sleeve 42.

While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
